As a buyer, it will cost you nothing to hire a real estate professional like me to help you find and purchase a home--your Realtor will likely get a portion of the commission the seller pays to his Realtor. 

Interview the agent who will be working for you and discuss the following:

Would the agent provide referrals from past clients?

Is the agent using the latest technology?  

How will the agent keep you informed of new property listings? 

How well does the agent know financing options, current property inventory, and future growth plans of the community?

Does the agent's broker have a buyer service guarantee? 

Does the agent's broker have a Concierge Program?
